Virtual Currency Remittance with Account Discrimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual currency management systems lack the ability to effectively limit the range of remittees, making it difficult to restrict the usage of virtual currency to specific regions or time-limited areas, which is necessary for scholarships or local area promotions.
Innovation Solution
A virtual currency remittance method that utilizes a blockchain and a database to manage account discrimination information, balance information, and remittable account information, allowing for the execution of transactions only when the remittance amount is within the account balance and meets specific use or condition criteria, thereby limiting the range of remittees and uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual currency is issued for local area promotion or scholarship, then the purpose of the virtual currency can be achieved, but the system lacks the ability to limit the range of remittees and control usage
Solution Approach 1:
The patent segments the account management by introducing account discrimination information that divides accounts into different categories (e.g., scholarship accounts, promotional accounts, personal accounts). This segmentation enables the system to apply different remittance rules to different account types, thereby limiting the range of remittees while maintaining reliable control over virtual currency usage for specific purposes.
Solution Approach 2:
The patent implements local quality by assigning specific properties to different account types through account discrimination information. Each account type has its own set of characteristics (such as permissible remittees, time limits, regional restrictions) that are stored and processed locally in the database, enabling differentiated control strategies for different virtual currency allocations without affecting other accounts.
2Ease of operation
If the system allows free remittance to any account, then ease of operation is improved, but the ability to restrict usage to specific regions or time-limited areas is lost
Solution Approach 1:
The patent applies preliminary action by pre-configuring account discrimination information and remittance rules in the database before the remittance operation occurs. When a user initiates a remittance, the system automatically retrieves the relevant account discrimination information and evaluates whether the remittance complies with the pre-set restrictions (such as permitted remittees, time limits, regional constraints). This preliminary setup maintains ease of operation while ensuring reliable restriction enforcement without requiring manual intervention.
Solution Approach 2:
The patent introduces account discrimination information as an intermediary element between the remittance operation and the actual currency transfer. This intermediary layer automatically evaluates remittance requests against predefined rules and mediates the transaction by allowing or blocking it based on compliance with account-specific restrictions. This mediator maintains user-friendly operation while ensuring reliable control over virtual currency usage.
3Ease of operation
If scholarship or promotional virtual currency is provided without remittance limits, then convenience is improved, but the risk of waste or misuse increases
Solution Approach 1:
The patent implements preliminary anti-action by pre-establishing account discrimination information that defines permissible remittance targets and conditions before the virtual currency is distributed. When a remittance attempt is made, the system automatically checks whether the transaction complies with the pre-set restrictions (such as whether the remittee is an authorized student or employee, whether the transaction is within the valid time period, whether the amount is within the allocated limit). This preliminary protective measure prevents waste or misuse of scholarship or promotional virtual currency while maintaining convenient distribution through automated verification.
